In this paper, I will discuss the relevance of epistemology of disagreement to political disagreement. The two major positions in the epistemology of disagreement literature are the steadfast and the conciliationist approaches: while the conciliationist says that disagreement with one’s epistemic equals should compel one to epistemically “split the difference” with those peers, the steadfast approach claims that one can maintain one’s antecedent position even in the face of such peer disagreement. Martin Ebeling (...) applies a conciliationist approach to democratic deliberations, arguing that deliberative participants ought to pursue full epistemic conciliation when disagreeing with their peers on political questions. I argue that this epistemic “splitting the difference” could make participants vulnerable to certain cognitive biases. We might avoid these biases by paying more attention to the deliberative environment in which disagreement takes place. (shrink)

Article Summary. The epistemology of disagreement studies the epistemically relevant aspects of the interaction between parties who hold diverging opinions about a given subject matter. The central question that the epistemology of disagreement purports to answer is how the involved parties should resolve an instance of disagreement. Answers to this central question largely depend on the epistemic position of each party before disagreement occurs. Two parties are equally positioned from an epistemic standpoint—namely, they are (...) epistemic peers—to the extent that they have roughly equal access to the evidence and comparable intellectual resources. When one party is epistemically better positioned than the other—that is, when one is an epistemic superior—it is widely agreed that this party should retain their belief while the other party—the epistemic inferior—should revise their opinion in the direction of what the epistemic superior believes. Addressing the central question is a complex task when the disagreeing parties are epistemic peers. Three main answers can be distinguished. Conciliatory answers mandate that both parties revise—i.e. lower their confidence in—their beliefs upon the occurrence of peer disagreement. Steadfast answers allow both parties to retain their respective beliefs, thereby committing them to demote the epistemic position of the interlocutor. The third group of answers suggests that the solution to peer disagreement depends on whether either party is highly justified in holding their belief. If either party is highly justified, then it is rational that this party retains its view. If neither party is highly justified, both should revise. The epistemology of disagreement addresses further important questions such as: whether the occurrence of disagreement opens the doors to skepticism and/or relativism; what the consequences of epistemic disagreement on intellectual character are; what laypeople should do when experts disagree with each other; and whether disagreement among groups can be treated in the same way as disagreement among individuals.

How should one react when one has a belief, but knows that other people—who have roughly the same evidence as one has, and seem roughly as likely to react to it correctly—disagree? This paper argues that the disagreement of other competent inquirers often requires one to be much less confident in one’s opinions than one would otherwise be.

When people disagree about what is moral, we face an epistemological challenge—when the answer to a moral question is not obvious, how do we determine who is right? What if, under the circumstances, we do not have the means to show one party or the other is right? In recent years, a number of epistemologists have turned their attention to the general epistemic problem of how to respond reasonably to disagreement, and we can look to their work for guidance. (...) While there remains significant disagreement about how to respond to disagreement, I will focus on what I take to be the best position in the debate, known as the “Conciliatory” position (or “Conciliation” for short), which holds that parties to a disagreement should become less confident of their initial opinions to some degree, according to the credibility of the parties involved. Conciliation, if interpreted straightforwardly, has some counter-intuitive implications for unpopular opinions, including unpopular moral judgments. If a moral non-conformist becomes somewhat less confident of her view in response to each disagreement with a presumed epistemic peer, she will eventually have such a low degree of confidence in her initial view that she will effectively have switched positions. This result is troubling because almost everyone accepts moral views that were non-conforming views at some point in time, and these views probably would not have become widespread if non-conformists had changed their positions. I propose a modified version of Conciliation which would enable moral non-conformists to engage in cautious “experiments in living.” This modified view, I argue, is reasonable for those who are concerned, not only with correcting their own mistaken moral views, but with promoting moral progress in general.

This is a collective study of the epistemic significance of disagreement: twelve contributors explore rival responses to the problems that it raises for philosophy. They develop our understanding of epistemic phenomena that are central to any thoughtful engagement with others' beliefs.

Disagreement is a ubiquitous feature of human life, and philosophers have dutifully attended to it. One important question related to disagreement is epistemological: How does a rational person change her beliefs (if at all) in light of disagreement from others? The typical methodology for answering this question is to endorse a steadfast or conciliatory disagreement norm (and not both) on a priori grounds and selected intuitive cases. In this paper, I argue that this methodology is misguided. (...) Instead, a thoroughgoingly Bayesian strategy is what's needed. Such a strategy provides conciliatory norms in appropriate cases and steadfast norms in appropriate cases. I argue, further, that the few extant efforts to address disagreement in the Bayesian spirit are laudable but uncompelling. A modelling, rather than a functional, approach gets us the right norms and is highly general, allowing the epistemologist to deal with (1) multiple epistemic interlocutors, (2) epistemic superiors and inferiors (i.e. not just epistemic peers), and (3) dependence between interlocutors.

Short introduction to the epistemology of disagreement.

One of the most salient features of forming beliefs in a social context is that people end up disagreeing with one another. This is not just an obvious fact about belief-formation; it raises interesting normative questions, especially when people become aware of the opinions of others. How should my beliefs be affected by the knowledge that others hold contrary beliefs? In some cases, the answer seems easy. If I have reason to think that my friend is much better informed than (...) I am, her dissent will often require substantial revision in my belief. If I have reason to think she's mentally deranged, her dissent may require no revision at all. But other cases are more difficult. For example, how confident should I be about my views in epistemology, knowing that they are denied by philosophers at least as intelligent, sane, knowledgeable, diligent and honest as I am? (shrink)

In disagreements about trivial matters, it often seems appropriate for disputing parties to adopt a ‘middle ground’ view about the disputed matter. But in disputes about more substantial controversies (e.g. in ethics, religion, or politics) this sort of doxastic conduct can seem viciously acquiescent. How should we distinguish between the two kinds of cases, and thereby account for our divergent intuitions about how we ought to respond to them? One possibility is to say that ceding ground in a trivial dispute (...) is appropriate because the disputing parties are usually epistemic peers within the relevant domain, whereas in a more substantial disagreement the disputing parties rarely, if ever, qualify as epistemic peers, and so ‘sticking to one’s guns’ is usually the appropriate doxastic response. My aim in this paper is to explain why this way of drawing the desired distinction is ultimately problematic, even if it seems promising at first blush. (shrink)

Martin Ebeling argues that a popular theory in the epistemology of disagreement--conciliationism--supports an egalitarian approach to politics. This view is mistaken for two reasons. First, even if political parties have the epistemic value that Ebeling claims, voters should not regard each other as epistemic peers--which conciliationism requires that they do. The American electorate is strikingly heterogeneous in both its knowledgeability and its rationality, and so the necessary epistemic parity relation does not hold. Second, for technical reasons, the beliefs (...) that a rational voter arrives at after conciliating with his peers do not, in general, accord with the results of egalitarian decision procedures. As its theory currently stands, the epistemology of disagreement does not support egalitarian politics. (shrink)

Abstract: Recent years have witnessed a revival of interest in relativism. Proponents have defended various accounts that seek to model the truth-conditions of certain propositions along the lines of standard possible world semantics. The central challenge for such views has been to explain what advantage they have over contextualist theories with regard to the possibility of disagreement. I will press this worry against Max Kölbel’s account of faultless disagreement. My case will proceed along two distinct but connected lines. (...) First, I will argue that the sense of faultlessness made possible by his relativism conflicts with our intuitive understanding of disagreement. And second, that his meta-epistemological commitments are at odds with the socio-epistemic function of disagreement. This latter problem for relativistic accounts of truth has thus far been largely ignored in the literature. (shrink)

This article is about the implications of a conciliatory view about the epistemology of peer disagreement for our moral beliefs. Many have endorsed a conciliatory view about the epistemology of peer disagreement according to which if we find ourselves in a disagreement about some matter with another whom we should judge to be our epistemic peer on that matter, we must revise our judgment about that matter. This article focuses on three issues about the implications (...) of conciliationism for our moral beliefs. The first is whether there is an asymmetry between the implications of conciliationism for the epistemic status of our moral beliefs and the implications of conciliationism for the epistemic status of our non-moral beliefs; for instance, some have argued that conciliationism leads to epistemological moral skepticism but not to epistemological nonmoral skepticism. The second is what the implications of conciliationism are for the epistemic status of particular moral beliefs. The third is whether conciliationism's impact on the epistemic status of our moral beliefs has practical implications. (shrink)

In this paper I argue for a version of the Total Evidence view according to which the rational response to disagreement depends upon one's total evidence. I argue that perceptual evidence of a certain kind is significantly weightier than many other types of evidence, including testimonial. Furthermore, what is generally called "The Uniqueness Thesis" is actually a conflation of two distinct principles that I dub "Evidential Uniqueness" and "Rationality Uniqueness." The former principle is likely true but the latter almost (...) certainly false. Seeing why the Rationality Uniqueness fails opens the door to seeing how mutual reasonable disagreement is possible even among those who share the same evidence. (shrink)

This paper approaches the current epistemological debate on peer disagreement from a neo-Pyrrhonian perspective, thus adopting a form of skepticism which is more radical than those discussed in the literature. It makes use of argumentative strategies found in ancient Pyrrhonism both to show that such a debate rests on problematic assumptions and to block some maneuvers intended to offer an efficacious way of settling a considerable number of peer disputes. The essay takes issue with three views held in the (...) peer disagreement debate: there is an objective fact of the matter about at least most controversial questions; we possess theory-neutral evidence bearing on those questions which grants us access to the truth of the matter; and many peer controversies are resolved by attending to which disputant has correctly evaluated the objective evidence. With respect to the first two views, it is argued that the belief in both objective facts and theory-neutral evidence is subject to fierce dispute, and should not therefore be taken for granted in the discussion of peer disagreement. As for the third view, it is argued that from either a first- or a third-person perspective, there seems to be epistemic symmetry between the disputants which makes it necessary to suspend judgment.

This is an introduction to the volume The Epistemology of Group Disagreement (Routledge, forthcoming), (eds.) F. Broncano-Berrocal and J.A. Carter.

How much should your confidence in your beliefs be shaken when you learn that others – perhaps 'epistemic peers' who seem as well-qualified as you are – hold beliefs contrary to yours? This article describes motivations that push different philosophers towards opposite answers to this question. It identifies a key theoretical principle that divides current writers on the epistemology of disagreement. It then examines arguments bearing on that principle, and on the wider issue. It ends by describing some (...) outstanding questions that thinking about this issue raises. (shrink)

According to conciliatory views about the epistemology of disagreement, when epistemic peers have conflicting doxastic attitudes toward a proposition and fully disclose to one another the reasons for their attitudes toward that proposition (and neither has independent reason to believe the other to be mistaken), each peer should always change his attitude toward that proposition to one that is closer to the attitudes of those peers with which there is disagreement. According to pure higher-order evidence views, higher-order (...) evidence for a proposition always suffices to determine the proper rational response to disagreement about that proposition within a group of epistemic peers. Using an analogue of Arrow's Impossibility Theorem, I shall argue that no conciliatory and pure higher-order evidence view about the epistemology of disagreement can provide a true and general answer to the question of what disagreeing epistemic peers should do after fully disclosing to each other the (first-order) reasons for their conflicting doxastic attitudes.

The conciliationist and steadfast approaches have dominated the conversation in the epistemology of disagreement. In this paper, drawing on Jennifer Lackey’s justificationist approach and the casuistry paradigm in medical ethics, I will develop a more contextual epistemology of political disagreement. On this account, a given political disagreement’s scope, domain, genealogy, and consequence can be helpful for determining whether we should respond to that disagreement at the level of our confidence, beliefs, or with policy. Though (...) some may argue that responding with policy is a practical consideration instead of an epistemic matter, I argue that even policy responses to disagreements have an epistemic dimension to them that we should not ignore.

The influence of Wittgenstein’s work in the study of deep disagreements has been dominated by On Certainty. Since the metaphor of ‘hinges’ plays a central role in the scholarship of On Certainty, a Wittgensteinian theory of deep disagreements is assumed to be based on hinge epistemology. This means that a disagreement would be deep because it concerns parties with conflicting hinges. When we shift our attention to a different part of Wittgenstein’s oeuvre, however, another picture of deep disagreements (...) emerges. This article proposes a new Wittgensteinian approach to disagreements through the analysis of the Lectures on Religious Belief. Some of the disagreements that Wittgenstein and his pupils discuss in these lectures are deep, but not because they are grounded in different hinges, but because they are disagreements about pictures.

In this paper, I provide a characterisation of a neglected form of humility: magnanimous humility. Unlike most contemporary analyses of humility, magnanimous humility is not about limitations but instead presupposes that one possesses some entitlement in a context. I suggest that magnanimous intellectual humility (IH) consists in a disposition to appropriately refrain from exercising one’s legitimate epistemic entitlements because one is appropriately motivated to pursue some epistemic good. I then shown that Magnanimous IH has an important role to play in (...) contexts of disagreement and oppression. It calls on knowing parties to refrain from pressing their epistemic entitlements to facilitate mutual understanding. And it is a virtue that oppressed persons have good reason to cultivate to develop meta-lucidity in themselves and others. (shrink)

A popular argument is that peer disagreement about controversial moral topics undermines justified moral belief in a way that peer disagreement about non-moral topics does not undermine justified non-moral belief. Call this argument the argument for moral skepticism from peer disagreement. Jason Decker and Daniel Groll have recently made a companions in guilt response to this argument. Decker and Groll argue that if peer disagreement undermines justified moral belief, then peer disagreement undermines much non-moral justified (...) belief; if the argument for moral skepticism from peer disagreement succeeds, then a kind of non-moral skepticism holds too. And we should not hold that the status of such non-moral beliefs are undermined by peer disagreement. In this paper, I shows that Decker and Groll’s companions in guilt argument fails. I then draw out the implications of my argument for the epistemology of disagreement and the epistemology of moral disagreement more generally. For instance, I then argue that peer disagreement about morality does not undermine all justified moral belief but that peer disagreement about morality does preclude most moral beliefs from being justified and constituting knowledge in a way that peer disagreement about non-moral topics does not preclude most non-moral beliefs from being justified and constituting knowledge.

Suppose you and I are equally well informed on some factual issue and equally competent in forming beliefs on the basis of the information we possess. Having evaluated this information, each of us independently forms a belief on the issue. However, since neither of us is infallible, we may end up with contrary beliefs. How should I react if I discover that we disagree in this way? According to conciliatory views in the epistemology of disagreement, I should modify (...) my original opinion by moving closer to your opinion. According to steadfast views, I should not.In the past decade or so, this issue has been addressed in hundreds of journal articles and a number of edited collections. The literature... (shrink)

An important principle in the epistemology of disagreement is Independence, which states, “In evaluating the epistemic credentials of another’s expressed belief about P, in order to determine how (or whether) to modify my own belief about P, I should do so in a way that doesn’t rely on the reasoning behind my initial belief about P” (Christensen 2011, 1-2). I present a series of new counterexamples to both Independence and also a revised, more widely applicable, version of it. (...) I then formulate and endorse a third version of Independence that avoids those counterexamples. Lastly, I show how this third version of Independence reveals two new ways one may remain steadfast in the face of two real life disagreements: one about God’s existence and one about moral realism.

Trust is a topic of longstanding philosophical interest. It is indispensable to every kind of coordinated human activity, from sport to scientific research. Even more, trust is necessary for the successful dissemination of knowledge, and by extension, for nearly any form of practical deliberation and planning. Without trust, we could achieve few of our goals and would know very little. Despite trust’s fundamental importance in human life, there is substantial philosophical disagreement about what trust is, and further, how trusting (...) is normatively constrained and best theorized about in relation to other things we value. This entry is divided into three sections, which explore key (and sometimes interconnected) ethical and epistemological themes in the philosophy of trust: (1) The Nature of Trust; (2) The Normativity of Trust, and (3) The Value of Trust.

Disagreement is one of the deepest and most pervasive topics in philosophy, arguably its very bedrock, and is an ever-increasing feature of politics, ethics, public policy, science and many other areas. Despite the omnipresence of disagreement, the topic itself has received relatively little sustained examination. In this outstanding handbook a team of international contributors examines the philosophy of disagreement and how it extends to debates in public policy and science. Comprising forty-one chapters by an international team of (...) contributors, the Handbook is divided into six clear parts: Philosophy of Disagreement Epistemology of Disagreement Disagreement about Science Moral Disagreement Disagreement in Politics Disagreement in Public Policy Within these sections key topics are examined, including: skepticism, truth, pluralism, feminist philosophy, experimental philosophy, epistemology of peer disagreement, rationality, intellectual virtue, relativism, realism, instrumentalism, scientific method and perspectivism. Ideal for those studying and researching philosophy, especially epistemology, ethics and philosophy of science, this handbook will also be of interest to those in related disciplines such as politics, social policy, and law.

There has been a recent explosion of interest in the epistemology of disagreement. Much of the recent literature is concerned with a particular range of puzzle cases (discussed in the Cases section of my paper). Almost all of the papers that contribute to that recent literature make mention of questions about religious disagreement in ways that suggest that there are interesting connections between those puzzle cases and real life cases of religious disagreement. One important aim of (...) my paper is to cast doubt on that suggestion. More generally, the aim of my paper is to give a reasonably full account of the recent literature on the epistemology of disagreement, and then to give a serious discussion of some of the epistemological issues that are raised by real world religious disagreements.

The paper begins by drawing a number of ‘levels’ distinctions in epistemology. It notes that a theory of knowledge must be an attempt to obtain knowledge . It is suggested that we can make sense of much of the work found in analytic theory of knowledge by seeing three framework assumptions as underpinning this work. First, that to have philosophical knowledge of knowledge requires us to have an analysis. Second, that much of what we require from a theory of (...) knowledge may be obtained by developing such analyses of first-order, concrete, empirical, propositional knowledge. Third, that the final arbiter of the correctness of such analyses is to be the carefully examined intuitions of the epistemologist. The paper attacks each aspect of this framework on the ground that this methodology will precisely not give us knowledge . In passing, comparisons are drawn with arguments that led to the demise of phenomenalism. The paper concludes with remarks about realism/anti-realism and consensus/disagreement in analytic epistemology. The paper recommends that we seek to develop theories of knowledge rather than analyses, and defends the position that such theories will precisely not be analyses. (shrink)

Richard Feldman’s “Reasonable Religious Disagreements” launched debates about the epistemic significance of disagreement that have been a dominant point of discussion in epistemology as of late. While most of these debates have been concerned with disagreement more generally, Feldman’s original focus was religious disagreement, and John Pittard returns the focus to religious disagreement in Disagreement, Deference, and Religious Commitment. Pittard’s book delves deeply into debates about the significance of disagreement with a foot in (...) both epistemology and philosophy of religion. It is the first book to look at these issues as they are being addressed within each of these sub-disciplines and is sure to be a significant contribution to the debates in both sub-fields. (shrink)

Conversation, dialogue, reasonable disagreement, and the acquisition of knowledge through the words of others, all of this has always been at the center of philosophers’ concerns since the emergence of philosophy in Ancient Greece. It is also important to recognize that in contemporary philosophy, marked by the linguistic turn, there is a wealth of intellectual production on ethical, psycho-linguistic, logical-linguistic, and pragmatic aspects of the conversation. Despite all this, this is the first collection of texts dedicated exclusively to the (...) strictly epistemic aspects of this phenomenon which is so decisive for the very constitution of our humanity. This book brings together the contributions of fifteen leading philosophers on some of the most relevant issues of what we could call the Epistemology of Conversation. (shrink)

To speak of being religious lucky certainly sounds odd. But then, so does “My faith holds value in God’s plan, while yours does not.” This book argues that these two concerns — with the concept of religious luck and with asymmetric or sharply differential ascriptions of religious value — are inextricably connected. It argues that religious luck attributions can profitably be studied from a number of directions, not just theological, but also social scientific and philosophical. There is a strong tendency (...) among adherents of different faith traditions to invoke asymmetric explanations of the religious value or salvific status of the home religion vis-à-vis all others. Attributions of good/bad religious luck and exclusivist dismissal of the significance of religious disagreement are the central phenomena that the book studies. Part I lays out a taxonomy of kinds of religious luck, a taxonomy that draws upon but extends work on moral and epistemic luck. It asks: What is going on when persons, theologies, or purported revelations ascribe various kinds of religiously-relevant traits to insiders and outsiders of a faith tradition in sharply asymmetric fashion? “I am saved but you are lost”; “My religion is holy but yours is idolatrous”; “My faith tradition is true, and valued by God, but yours is false and valueless.” Part II further develops the theory introduced in Part I, pushing forward both the descriptive/explanatory and normative sides of what the author terms his inductive risk account. Firstly, the concept of inductive risk is shown to contribute to the needed field of comparative fundamentalism by suggesting new psychological markers of fundamentalist orientation. The second side of what is termed an inductive risk account is concerned with the epistemology of religious belief, but more especially with an account of the limits of reasonable religious disagreement. Problems of inductively risky modes of belief-formation problematize claims to religion-specific knowledge. But the inductive risk account does not aim to set religion apart, or to challenge the reasonableness of religious belief tout court. Rather the burden of the argument is to challenge the reasonableness of attitudes of religious exclusivism, and to demotivate the “polemical apologetics” that exclusivists practice and hope to normalize.

I first argue that, contrary to many atheistic philosophers, there is good reason to think the typical theistic philosopher’s retaining of her theism when faced with the Problem of Evil is comparatively epistemically upstanding even if both atheism is true and the typical theistic philosopher has no serious criticism of the atheist’s premises in the PoE argument. However, I then argue that, contrary to many theistic philosophers, even if theism is true, the typical theistic philosopher has no good non-theistic reasons (...) for rejecting any of the atheist’s premises, and she has good non-theistic reasons in favor of the atheist’s premises. In that respect, it’s extremely difficult for the theistic philosopher to respond to the PoE in an informative, non-question-begging way. I close by considering whether theistic philosophers should reject my second thesis. (shrink)

This chapter covers contemporary work on disagreement, detailing both the conceptual and normative issues in play in the debates in mainstream analytic epistemology, and how these relate to religious diversity and disagreement. §1 examines several sorts of disagreement, and considers several epistemological issues: in particular, what range of attitudes a body of evidence can support, how to understand higher-order evidence, and who counts as an epistemic “peer”. §2 considers how these questions surface when considering disagreements over (...) religion, including debates over the nature of evidence and truth in religion, epistemic humility, concerns about irrelevant influences and about divine hiddenness, and arguments over exclusivism, inclusivism, and pluralism. Finally, §3 summarizes the contributors’ essays in this volume. (shrink)

Religious disagreements are widespread. Some philosophers have argued that religious disagreements call for religious skepticism, or a revision of one’s religious beliefs. In order to figure out the epistemic significance of religious disagreements, two questions need to be answered. First, what kind of disagreements are religious disagreements? Second, how should one respond to such disagreements? In this paper, I argue that many religious disagreements are cases of unconfirmed superiority disagreements, where parties have good reason to think they are not epistemic (...) peers, yet they lack good reason to determine who is superior. Such disagreements have been left relatively unexplored. I then argue that in cases of unconfirmed superiority disagreements, disputants can remain relatively steadfast in holding to their beliefs. Hence, we can remain relatively steadfast in our beliefs in such cases of religious disagreements. (shrink)

Although moral relativists often appeal to cases of apparent moral disagreement between members of different communities to motivate their view, accounting for these exchanges as evincing genuine disagreements constitutes a challenge to the coherence of moral relativism. While many moral relativists acknowledge this problem, attempts to solve it so far have been wanting. In response, moral relativists either give up the claim that there can be moral disagreement between members of different communities or end up with a view (...) on which these disagreements have no “epistemic significance” because they are always faultless. This paper introduces an alternative strategy: accounting for disagreement in terms of “metalinguistic negotiation”. It argues that this strategy constitutes a better solution to the challenge disagreement poses for moral relativists because it leads to a nuanced understanding of the epistemic significance of moral disagreement between members of different communities. The upshot is a novel account of disagreement for moral relativists that has consequences for how moral relativism should be understood. (shrink)

Disagreement is common: even informed, intelligent, and generally reasonable people often come to different conclusions when confronted with what seems to be the same evidence. Can the competing conclusions be reasonable? If not, what can we reasonably think about the situation? This volume examines the epistemology of disagreement. Philosophical questions about disagreement arise in various areas, notably politics, ethics, aesthetics, and the philosophy of religion: but this will be the first book focusing on the general epistemic (...) issues arising from informed disagreement. Ten leading philosophers offer specially written essays which together will offer a starting-point for future work on this topic. (shrink)

This is a short essay that presents what I take to be the main questions regarding the epistemology of disagreement.

Epistemologists have shown increased interest in the epistemic significance of disagreement, and in particular, in whether there is a rational requirement concerning belief revision in the face of peer disagreement. This article examines some of the general issues discussed by epistemologists, and then considers how they may or may not apply to the case of religious disagreement, both within religious traditions and between religious (and non-religious) views.

While the epistemic significance of disagreement has been a popular topic in epistemology for at least a decade, little attention has been paid to logical disagreement. This monograph is meant as a remedy. The text starts with an extensive literature review of the epistemology of (peer) disagreement and sets the stage for an epistemological study of logical disagreement. The guiding thread for the rest of the work is then three distinct readings of the ambiguous (...) term ‘logical disagreement’. Chapters 1 and 2 focus on the Ad Hoc Reading according to which logical disagreements occur when two subjects take incompatible doxastic attitudes toward a specific proposition in or about logic. Chapter 2 presents a new counterexample to the widely discussed Uniqueness Thesis. Chapters 3 and 4 focus on the Theory Choice Reading of ‘logical disagreement’. According to this interpretation, logical disagreements occur at the level of entire logical theories rather than individual entailment-claims. Chapter 4 concerns a key question from the philosophy of logic, viz., how we have epistemic justification for claims about logical consequence. In Chapters 5 and 6 we turn to the Akrasia Reading. On this reading, logical disagreements occur when there is a mismatch between the deductive strength of one’s background logic and the logical theory one prefers (officially). Chapter 6 introduces logical akrasia by analogy to epistemic akrasia and presents a novel dilemma. Chapter 7 revisits the epistemology of peer disagreement and argues that the epistemic significance of central principles from the literature are at best deflated in the context of logical disagreement. The chapter also develops a simple formal model of deep disagreement in Default Logic, relating this to our general discussion of logical disagreement. The monograph ends in an epilogue with some reflections on the potential epistemic significance of convergence in logical theorizing. (shrink)

This book has argued that problems of religious luck, especially when operationalized into concerns about doxastic risk and responsibility, can be of shared interest to theologians, philosophers, and psychologists. We have pointed out counter-inductive thinking as a key feature of fideistic models of faith, and examined the implications of this point both for the social scientific study of fundamentalism, and for philosophers’ and theologians’ normative concerns with the reasonableness of a) exclusivist attitudes to religious multiplicity, and b) theologically-cast but bias-mirroring (...) trait-ascriptions to religious insiders and outsiders. It is important to keep the descriptive/explanatory and normative concerns properly separated, but philosophy of luck and risk are relevant to both. More specifically, inductive risky theological strategies,we have argued, are a relevant concern both descriptively and normatively. The descriptive/explanatory relevance of measures of high inductive risk connects it with cognitive and social psychology of religion, while its normative relevance connects with critical concerns with epistemology of testimony, the epistemology of disagreement, and the ethics of belief. A research program to examine fideistic orientation and its relation to epistemically risky doxastic strategies is one of potentially numerous research programs on which philosophers and psychologists might work collaboratively. So this concluding chapter of our study culminates with the outline of a proposed research program at the intersection of shared concerns. I term this research program CICI, because it examines what lies at the intersection of CSR’s standing interest in the appeal of counter-intuitive ideas, and our own study’s focus on the fideistic penchant for counter-inductive thinking. Religious Studies scholars typically focus on particular traditions and teachings, while CSR scholars tend to eschew such content-focused approaches in favor of a study of evolutionary and hence generic or trans-religious functions and processes. I argue that CICI has the added benefit of effectively mediating this generic-specific contrast between CSR and Religious Studies, allowing CSR research to be more closely connected with and relevant to comparative fundamentalism.

I investigate the implication of the truth-relativist’s alleged ‘ faultless disagreements’ for issues in the epistemology of disagreement. A conclusion I draw is that the type of disagreement the truth-relativist claims to preserve fails in principle to be epistemically significant in the way we should expect disagreements to be in social-epistemic practice. In particular, the fact of faultless disagreement fails to ever play the epistemically significant role of making doxastic revision rationally required for either party in (...) a disagreement. That the truth-relativists’ disagreements over centred content fail to play this epistemically significant role that disagreements characteristically play in social epistemology should leave us sceptical that disagreement is what the truth-relativist has actually preserved.

The debate on the epistemology of disagreement has so far focused almost exclusively on cases of disagreement between individual persons. Yet, many social epistemologists agree that at least certain kinds of groups are equally capable of having beliefs that are open to epistemic evaluation. If so, we should expect a comprehensive epistemology of disagreement to accommodate cases of disagreement between group agents, such as juries, governments, companies, and the like. However, this raises a number (...) of fundamental questions concerning what it means for groups to be epistemic peers and to disagree with each other. In this paper, we explore what group peer disagreement amounts to given that we think of group belief in terms of List and Pettit’s ‘belief aggregation model’. We then discuss how the so-called ‘equal weight view’ of peer disagreement is best accommodated within this framework. The account that seems most promising to us says, roughly, that the parties to a group peer disagreement should adopt the belief that results from applying the most suitable belief aggregation function for the combined group on all members of the combined group. To motivate this view, we test it against various intuitive cases, derive some of its notable implications, and discuss how it relates to the equal weight view of individual peer disagreement.

In “The Logic of Deep Disagreements,” Robert Fogelin claims that parties to a deep disagreement lack the common ground needed for arguments to work, making the disagreement impervious to rational resolution. Although Fogelin’s article received numerous responses, there has been no attempt to elucidate the epistemological theory behind Fogelin’s theses. In this article, I examine Fogelin’s theory of deep disagreements in light of his broader philosophy. The picture that emerges is that of relativism of distance, à la Bernard (...) Williams. By interpreting Fogelin’s theory as relativism of distance, it avoids some of the critiques that have been raised against it. (shrink)

Disagreement among experts is a central topic in social epistemology. What should an expert do when confronted with the different opinion of an epistemic peer? Possible answers include the steadfast view (holding to one’s belief), the abstemious view (suspending one’s judgment), and moderate conciliatory views, which specify criteria for belief change when a peer’s different opinion is encountered. The practice of Delphi techniques in healthcare, medicine, and social sciences provides a real-life case study of expert disagreement, where (...) disagreement is gradually transformed into consensus. An analysis of Delphi shows that moderate conciliatory views are descriptively more adequate than rival views. However, it also casts doubt on whether the debate in social epistemology is explanatory relevant vis-à-vis real life cases of expert disagreement, where consensus replaces truth, and acceptance is more explanatorily relevant than belief.

Over the past decade, attention to epistemically significant disagreement has centered on the question of whose disagreement qualifies as significant, but ignored another fundamental question: what is the epistemic significance of disagreement? While epistemologists have assumed that disagreement is only significant when it indicates a determinate likelihood that one’s own belief is false, and therefore that only disagreements with epistemic peers are significant at all, they have ignored a more subtle and more basic significance that belongs (...) to all disagreements, regardless of who they are with—that the opposing party is wrong. It is important to recognize the basic significance of disagreement since it is what explains all manners of rational responses to disagreement, including assessing possible epistemic peers and arguing against opponents regardless of their epistemic fitness.

Philosophers disagree. A lot. Pervasive disagreement is part of the territory; consensus is hard to find. Some think this should lead us to embrace philosophical skepticism: skepticism about the extent to which we can know, or justifiably believe, the philosophical views we defend and advance. Most philosophers in the literature fall into one camp or the other: philosophical skepticism or philosophical anti-skepticism. Drawing on the insights of hinge epistemology, this paper proposes another way forward, an intermediate position that (...) appeals both to skeptical and anti-skeptical intuitions concerning the possibility and scope of philosophical knowledge. The main advantage of our account is that it’s able to recover some philosophical knowledge while also being compatible with philosophical skepticism. (shrink)

Politics is rife with motivated cognition. People do not dispassionately engage with the evidence when they form political beliefs; they interpret it selectively, generating justifications for their desired conclusions and reasons why contrary evidence should be ignored. Moreover, research shows that epistemic ability (e.g. intelligence and familiarity with evidence) is correlated with motivated cognition. Bjørn Hallsson has pointed out that this raises a puzzle for the epistemology of disagreement. On the one hand, we typically think that epistemic ability (...) in an interlocutor gives us reason to downgrade our belief upon learning that we disagree. On the other hand, if our interlocutor is under the sway of motivated cognition, then we have reason to discount his opinion. In this paper, I argue that Hallsson's puzzle is solved by adopting a Bayesian approach to disagreement. If an interlocutor is under the sway of motivated cognition, his disagreement should not affect our beliefs--no matter his ability. Because we implicitly and to high accuracy know his beliefs before he reveals them to us, disagreement provides us with no new information on which to conditionalize. I advance a model which accommodates the motivated cognition dynamic and other key epistemic features of disagreement. (shrink)

Modest pessimism about philosophical progress is the view that while philosophy may sometimes make some progress, philosophy has made, and can be expected to make, only very little progress (where the extent of philosophical progress is typically judged against progress in the hard sciences). The paper argues against recent attempts to defend this view on the basis of the pervasiveness of disagreement within philosophy. The argument from disagreement for modest pessimism assumes a teleological conception of progress, according to (...) which the attainment of true answers to the big philosophical questions, or knowledge of them, is the primary goal of philosophy. The paper argues that this assumption involves a misconception of the goal of philosophy: if philosophy has a primary goal, its goal is the understanding of philosophical problems rather than knowledge of answers to philosophical questions. Moreover, it is argued that if the primary goal of philosophy is such understanding, then widespread disagreement within philosophy does not indicate that philosophy makes little progress. (shrink)

We call systematic disputes that are particularly hard to resolve deep disagreements. We can divide most theories of deep disagreements in analytic epistemology into two camps: the Wittgensteinian view and the fundamental epistemic principles view. This essay analyzes how both views deal with two of the most pressing issues a theory of deep disagreement must address: their source and their resolution. After concluding that the paradigmatic theory of each camp struggles on both fronts, the essay proceeds to show (...) that, despite their differences, these theories share some core assumptions and think of deep disagreements similarly: as grounded in fundamental epistemic differences between the parties. This underlying conception of deep disagreements the author calls “the fundamental model.” The essay provides reasons to be wary of this conception, and hence, mainstream epistemologists’ treatment of the issue.
